Just checked the VicEmergency website and took this screenshot of the wind-direction[s] around Melbourne at the moment:
The little arrows indicate where the wind is coming from, and where it’s going to. The bottom of the picture is ‘south’ so you can see that in the lavender coloured areas down the bottom, wind direction is a steady ‘south easterly’ – i.e. coming from the south and east. In the pale areas, however, the wind is all over the place. Literally.
Why bother with wind direction?
Because you need to know whether a bushfire is being blown towards you or away from you.
To see the wind direction overlay on the VicEmergency map, click the Filter option as shown:
This will open a drop down list. Scroll down the list and click ‘wind direction’. This will display the lavender map at the top of this post.
To get rid of the wind direction overlay, open the Filter menu again and select ‘None’.
If you’re looking at the VicEmergency app on your phone, you have to tap your watch zone first. Once it opens, the Filter option is located up the top on the right-hand side of the screen [next to the ?].
Tap Filter and select the option for wind direction as for the website.
Given how dry and horrible this Spring has been, I think I’ll be keeping that wind direction overlay on at all times.
